    What does Luyuan provide that Basen doesn't? I don't see a justification for the difference in price. They both are providing the same batteries, packed well.

    Several of us have used Basen. I don't know about your batteries, but I assume they were also bought from EVE as matched. Basen also warehoused LF280s in CA so you can get shortened delivery times. Cost me less to get 280s from CA via Basen then from China with Luyuan. I received my...

    Lishen 270ah-272ah cell group buy.

    Huh, never heard of such a thing? Did they give you a reason? Do they use a delivery service that doesn't go to Idaho?

    Airstreamer looking for some advice on mounting to a curved roof

    Generally an accident involving pedestrians is low speed and wouldn't cause even poorly installed panels to come off. Even if a vehiicle accident in a crowded pedestrian area, I just don't think inertia would exist. In high speed crashes the panels are probably the least of the worries as the...

    Airstreamer looking for some advice on mounting to a curved roof

    When working with a trailer/motorhome roof, there are trusses to bolt into. I think you were overboard on your install. I am making a rack out of 1.5" square aluminum which will be attached to the trusses and the panels will attach to the square. Instead of four holes in the roof at random...

    Shenzhen Basen vs Shenzen Luyuan Lifepo4?

    You still deal with China. They can sell out of their Shenzhen location or out of the US warehouse. They might have also warehoused elsewhere as well. Basen Like with the other vendors, use the chat function which will get you into sales. I worked with Emily and another user here got...

    Airstreamer looking for some advice on mounting to a curved roof

    Seems the best way to route from my roof to the intended battery location is going down through a closet on the left front of the trailer. When I install the second set of panels, they will be over that location, but I am installing the panels down the right side of the roof, so I will need to...

    Airstreamer looking for some advice on mounting to a curved roof

    My panels will be in a row along the edge of the roof and all interconnections will be done with tiewraps under the rack they will be mounted to. I was only asking about the best way to get from there across the roof, and that would be two wires, i.e. positive and negative. Don't know where...

    Shenzhen Basen vs Shenzen Luyuan Lifepo4?

    I have mentioned Basen (and it is in the title) in many posts here and that they have matched EVE LF280 batteries domestically for less than buying from some vendors in China. Another user on here just received 8 cells from the same vendor at my suggestion. He is thrilled with them as I was...

    Airstreamer looking for some advice on mounting to a curved roof

    I found a company, Electriduct that makes a UV resistant wire loom tubing but only in black. They make white tubing, but not UV resistant. Compared to having red and black cables on the roof, a black wire loom isn't horrible. I don't know many people who are 10' tall and will see it :)...

    Airstreamer looking for some advice on mounting to a curved roof

    Chris was replying to my question about attaching the PV cabling to the roof, not to the panels. The white roof wouldn't be as hot so adhesives inappropriate for the back of a solar panel still could be ok for the roof. Chris: Is the PV cable in your picture regular PV cable as it isn't red...

    So Eternabond isn't SW compatible :) What is the preferred or suggested method to adhere the PV cables to the roof other than when I can tiewrap them?

    We can also assume that in some cases the surface prep wasn't done properly or the surface wasn't something appropriate for VHB. I have suction cup things come loose frequently. The saliva dries up, the bond is lost, off it comes.

    RV Setup Plan - 6kWh Lithium and 1,600w of Solar

    Seems the panels were put up in a convenient manner without regard to ever wanting to install more... No problem if you don't ever want more panels but clearly not space-optimized.

    RV Setup Plan - 6kWh Lithium and 1,600w of Solar

    I have room on my 22' trailer for 1200w and if I use the rack area, another 4-600w. That is working around an antenna, two maxairs, the AC, two sunlights, and the propane exhaust. If you have 4' more of trailer, and the same obstacles I do, then two more panels than me would be easy.

    I thought about VHB. Wasn't sure it was strong enough, and was worried it was too strong :) Wouldn't want to remove the system and have VHB tear my roof off :(

    Who should I purchase my Off Grid Setup from?

    Even Andy from Off Grid garage searches around town for used panel bargains. I am glad there are people who buy new and eat the depreciation so I can come along and get a bargain, thanks!

    Who should I purchase my Off Grid Setup from?

    I don't know that buying used panels is so unlike anything else you buy used. Generally, if you buy right, you are getting most of the value out of an item without paying full price, like paying 1/3 cost for 80% life. I bought a used house, a used SUV, a used travel trailer, I am about deals...

    Ordered 8 EVE "new" 280Ah cells from Shenzhen Luyuan

    Or Basen in my case, but Basen pre-ordered cell to have them in inventory for when an order is placed, or in my case, already have them in the US for quicker delivery. Thanks

    ABS Battery Box for 8S 280 ah 24 Volt Battery

    my 8 cell battery is 12X14....fits easily with room for BMS... I am not saying it works for everyone's battery, but I thought it was appropriate for the battery pack being discussed.

    EVE 280A Load Capacity Testing Help Wanted

    My Lishen cells weren't bought when there was so much emphasis on matching cells and so matching wasn't even the dialogue. When I bought my newer EVE cells, the vendor (like Amy) claimed matched cells, but then we discovered that their idea of matching and what people said were the criteria for...

    EVE 280A Load Capacity Testing Help Wanted

    The tester connects to the 120V outlet which is connected to a breaker :) If I was to add a fuse, I don't know if I have the correct fuse, but wouldn't that also add resistance and further slow the charge?

    Compression, Balancing, Reconfigure the pack

    Cool beans....I can't do 16 at a time since I am still load testing the first eight. I am OK charging the second eight at once which I am doing now.

    EVE 280A Load Capacity Testing Help Wanted

    I have the Victron shunt with BM712 meter, collecting dust. The top balancing took awhile which is how I got them all to 3.65. With it taking a day to load test one cell, it can be arduous. Have a secret for you....you can actually go to work, eat and sleep while charging and testing is going...

    EVE 280A Load Capacity Testing Help Wanted

    Way too complicated for my senile mind. My inverter is still untouched...on the bench, never seen a wire. Same with my shunt, all just sitting there waiting for the build I keep procrastinating on. For those who are following my antics, I began testing the Lishen 272A cells from Michael I...

    EVE 280A Load Capacity Testing Help Wanted

    I only have a .0001C tester :) It is the 150W load tester that only draws 12A with my setup. Does that make it a .08 load tester if my math is right?

    Airstreamer looking for some advice on mounting to a curved roof

    My concern with that is hitting tree branches, etc... The AC is the tallest thing and I thought of installing them at that height, but having the panels "way" up in the air just means trouble for me. As it is, it is hard to get through the McDonalds drive-thru.
